Oh Noes! Window to avoid 1.5°C of warming will close before 2030 if emissions are not reduced

From the Imperial College of London and the “doom is always just a few years away” department comes this snoozer. – Anthony


Without rapid carbon dioxide emission reductions, the world has a 50% chance of locking in 1.5°C of warming before 2030, according to a study led by Imperial College London researchers.

The study, published today in Nature Climate Change, is the most up-to-date and comprehensive analysis of the global carbon budget. The carbon budget is an estimate of the amount of carbon dioxide emissions that can be emitted while keeping global warming below certain temperature limits.

The Paris Agreement aims to limit global temperature increase to well below 2°C above preindustrial levels and pursue efforts to limit it to 1.5°C. The remaining carbon budget is commonly used to assess global progress against these targets.

The new study estimates that for a 50% chance of limiting warming to 1.5°C, there are less than 250 gigatonnes of carbon dioxide left in the global carbon budget.

The researchers warn that if carbon dioxide emissions remain at 2022 levels of about 40 gigatonnes per year, the carbon budget will be exhausted by around 2029, committing the world to warming of 1.5°C above preindustrial levels.

The finding means the budget is less than previously calculated and has approximately halved since 2020 due to the continued increase of global greenhouse gas emissions, caused primarily from the burning of fossil fuels as well as an improved estimate of the cooling effect of aerosols, which are decreasing globally due to measures to improve air quality and reduce emissions.

Dr Robin Lamboll, research fellow at the Centre for Environmental Policy at Imperial College London, and the lead author of the study, said: “Our finding confirms what we already know – we’re not doing nearly enough to keep warming below 1.5°C.

“The remaining budget is now so small that minor changes in our understanding of the world can result in large proportional changes to the budget. However, estimates point to less than a decade of emissions at current levels.

“The lack of progress on emissions reduction means that we can be ever more certain that the window for keeping warming to safe levels is rapidly closing.”

Dr Joeri Rogelj, Director of Research at the Grantham Institute and Professor of Climate Science & Policy at the Centre for Environmental Policy at Imperial College London, said: “This carbon budget update is both expected and fully consistent with the latest UN Climate Report.

“That report from 2021 already highlighted that there was a one in three chance that the remaining carbon budget for 1.5°C could be as small as our study now reports. 

“This shows the importance of not simply looking at central estimates, but also considering the uncertainty surrounding them.”

The study also found that the carbon budget for a 50% chance of limiting warming to 2°C is approximately 1,200 gigatonnes, meaning that if carbon dioxide emissions continue at current levels, the central 2°C budget will be exhausted by 2046.

There has been much uncertainty in calculating the remaining carbon budget, due to the influence of other factors, including warming from gasses other than carbon dioxide and the ongoing effects of emissions that are not accounted for in models. 

The new research used an updated dataset and improved climate modelling compared to other recent estimates, published in June, characterising these uncertainties and increasing confidence around the remaining carbon budget estimates.

The strengthened methodology also gave new insights into the importance of the potential responses of the climate system to achieving net zero.

‘Net zero’ refers to achieving an overall balance between global emissions produced and emissions removed from the atmosphere.

According to the modelling results in the study, there are still large uncertainties in the way various parts of the climate system will respond in the years just before net zero is achieved.

It is possible that the climate will continue warming due to effects such as melting ice, the release of methane, and changes in ocean circulation.

However, carbon sinks such as increased vegetation growth could also absorb large amounts of carbon dioxide leading to a cooling of global temperatures before net zero is achieved.  

Dr Lamboll says these uncertainties further highlight the urgent need to rapidly cut emissions. “At this stage, our best guess is that the opposing warming and cooling will approximately cancel each other out after we reach net zero.

“However, it’s only when we only when we cut emissions and get closer to net zero that we will be able to see what the longer-term heating and cooling adjustments will look like.

“Every fraction of a degree of warming will make life harder for people and ecosystems. This study is yet another warning from the scientific community. Now it is up to governments to act.”

Yes. Not that it matters; they’re all the same. It’s another tier added to the top-heavy edifice constructed of models on top of speculation on top of assertions based on other folks’ models, with only the smallest foundation of selected and manipulated observational data. It’s a very unstable edifice that needs to be propped up by more and more of these publicly funded, tendentious studies that endlessly recycle the same underlying assertions, and by an incessant torrent of propaganda from the media, and by decades of indoctrination in educational institutions at all levels from kindergarten to post-graduate, and by the pronouncements of our posturing politicians who think they’re being clever.

Like all unstable edifices, it will eventually collapse under its own weight. I would like to think that there will be some sort of civil society remaining after it does collapse.

Things are just now starting to unravel as the policies based on this edifice are starting to hurt regular people, and their real costs begin to emerge from the fog of obfuscation. Here’s an opinion piece about a new development at home in Canada that gives me some modest encouragement:

Trump didn’t lock down the U.S.

Trump gave State governors the responsibility for handling what happened in their States. Some governors imposed lockdowns, some didn’t.

My State, Oklahoma, had no state-wide mandates of any kind, as far as masks or travel was concerned.

Unfair comment. By the end of March, 2020 Trump was explicitly opposed to lockdowns. Perhaps all will remember his using the phrase, “The cure shouldn’t be worse than the disease when talking about lockdowns.

The ani-Trump slander in the covid era included claims that he recommended injecting bleach. The true history is that Trump was advised about a number of ways that the covid virus could be killed outside the body, including various chemicals such as common bleach and UV light.

Trump, not a scientist, nor pretending to be, asked the reasonable question whether medicines could be developed from this knowledge.

Trump haters went to town and lied about Trump’s comments and questions, which is no surprise, since Trump hatred has led many people to lie.

(Eg, read the whole transcript of his Charlottesville speech and seeTrump devoted a whole paragraph clarifying that he considered neoNazis evil and was not talking about them when he said there were “fine people” on both sides of the “tearing down statues” issue. Joe Biden to this day lies about that Trump speech).

I agree with you and Tom H, above. However, while it’s certainly unreasonable to expect leaders to be experts on everything, it’s not unreasonable to expect them to ask questions. To wit, Trump should have inquired about Ferguson’s track record at Imperial, which would have revealed that the former had a decades-long record of vastly overstating previous ‘pandemics’. At the very least, this would have defanged Fauci and Birx long enough for less partisan experts to weigh in on how best to respond to COVID.

“The Paris Agreement aims to limit global temperature increase to well below 2°C above preindustrial levels and pursue efforts to limit it to 1.5°C.”

The alarmists ALWAYS use this language – which is of course only a partial truth.

When they refer to the “preindustrial temperature”, they always mean the very cold temperature immediately preceding the industrial revolution.

The LIA appears to have been literally the coldest extended period during the entire Holocene.

The Holocene Climatic Optimum could also be used as the “preindustrial temperature” for purposes of comparison. Somehow they never pick the ripe cherries, only the bitter cherries.

Kevin was just joking around – but the temperature series is a joke when trying to use it to understand and model something as complicated as the world’s climate.

Pretend it’s something basic like the classic modeling exercise of a metal rod, chilled at one end with ice and heated on the other end with a flame of known BTUs or Joules. If you wanted to run live experiment in order to generate the data needed to test the computer model of the thermodynamics, wouldn’t you want to have at least 10 temperature probes down the length of the rod (30 to 100 cm long) and take temp readings every second in order to get a good profile spacially and temporally?

Now look at the whole planet and we want to model not only conductive but radiative and convective heat transfer, and the surface has a wide range of ‘materials’ all with different heat properties. I wouldn’t feel happy with a model of the Earth unless I had a million or more cells, and that would mean I had a million or more thermometers, measured every minute or hour, to compare to.

Or at least one for every degree square, which would still mean almost 130,000 stations measuring every hour.

How is one supposed model the climate when only looking at max/min data for stations that are mostly in the US, and a sizeable number in Australia, Canada, Brazil and India – and most of those would be at unsuitable locations like airports, military bases and such?

I think we could go farther than post-Wisconsin glaciation temperatures. By the abundance of life, proliferation, and their size indicating how well they ate, a case can be made that the Cambrian and the Jurassic temperatures were ‘climate optimum’ for life on this planet. Man is not the only one here; what right does this one species have to claim what climate is the correct one and what everything else should adapt to or perish?–and that we have a right to control it?

Exactly – the world was sea to sea rain forest during the Jurassic and/or Cretaceous periods (probably some exaggeration there admittedly), a super bio diverse and dense time, much more healthy then our period (healthy for the dinosaurs and insects but not for us) and it was about 10°C warmer and CO2 was at minimum 1500ppm, and even 2500ppm at times.

Were these terrifying windows open or closed during the Medieval, Roman and Minoan Warm Periods? Were they open or closed during the Holocene Climate Optimum? I am wondering how humans managed to survive such horrifying warm times. After all, we are all still here, aren’t we?

There have been 5 warm periods in the 5K or so years since the end of the Holocene Optimum.
The Egyptian, Minoan, Roman, Medieval and Modern.
Each warm period has been a little bit cooler than the previous, as has the cool period between them.
The time span between the end of the optimum as well as between each of the warm periods is right around 1000 years. This holds true for the gap between the Medieval and Modern warm periods.

The consistency of this gap does not prove that the Modern warm period is just a continuation of this series, however a pattern that has repeated 4 times, is likely to repeat a 5th.

If I read that correctly, she has at least tried to define what 1.5C means. Now if the world is really in a 2023-or-too-late situation then, does that mean I may tune out the cause if the world chooses or-too-late?

If 1.5C is the point at which we can start seeing changes caused by warmer temperatures, does that mean that at 1.4C and lower, we can’t see any changes.

It told the story of the Permian extinction event 252 M years ago, and of course C02 was the culprit, and naturally they did some preaching about CC (perfect opportunity). The way they present those episodes, with lots of comments from obviously progressive people about the evils of C02. The way they obsess about it is weird. And I bet none of those people have solar panels on the roof.

NOVA “Ancient Earth: INFERNO” Premieres Wednesday, October 25, 2023 at 9pm ET/8C
252 million years ago, the most devastating mass extinction of all time abruptly wiped out around 90% of all species on Earth. The culprits were the biggest volcanic eruptions the world has ever seen, emitting some 700 thousand cubic miles of magma and rock. Volcanic gases permeated the atmosphere and acidified the oceans while toxic gases destroyed the ozone layer, bathing the planet in destructive ultraviolet radiation. The event – now called “The Great Dying” – came close to wiping out all life on the planet. Follow scientists as they piece together geologic evidence from the deep past and clues from today’s ecosystems to discover how life made it through and evolved into the astonishing variety we see around us today.

What amazes and disturbs me is how they always want these things to have happened in an instant, eg. “the most devastating mass extinction of all time abruptly wiped out around 90% of all species on Earth”. My considered opinion is that the extinction actually took quite a long time – at least 35 minutes and possibly 100 million years[*]. That’s quite a lot of uncertainty, I know, but it’s a bit like the ECS range in the IPCC reports.
[*] The latter seems more likely, because if the extinction had been really abrupt then surely there would be no chickenosaur on the supermarket shelves today.

“However, carbon sinks such as increased vegetation growth could also absorb large amounts of carbon dioxide leading to a cooling of global temperatures before net zero is achieved. ”

It seems that no one is disagreeing with the fact that CO2 fertilization is greening the planet. All other things being equal, two plots of land–one with vegetation and one without–the one with vegetation is darker. Darker would reduce the associated albedo. That would tend to increase global temperatures vice decrease them. Of course, you would have to believe that global temperatures are a reality.

When this 1.5C nonsense first raised it’s silly head, it was 2.0C nonsense.
The original claim was also that if we got above 2.0C over 1850 (which was during the Little Ice Age) we would be getting to temperatures that were warmer than the Medieval Warm Period and would hence be unknown territory.

When the story changed from unknown territory to certain doom, I don’t know.
Anyways, a short time after it first appeared, it became obvious that the world was never going to reach the 2.0C threshold, so the doomsday threshold was dropped to 1.5C.

Still no evidence that anything bad is going to happen if we reach that mark.

BTW, most estimates of the Holocene Optimum put it as much as 3 to 5C above the depths of the LIttle Ice Age. They call the period an optimum, because life flourished during it.

They realise that it is just a MADE-UP number… pertaining to absolutely nothing.

Anyway, the time resolution of pre-industrial temperature proxies is maybe 50 year time steps, at best.

Comparing single day or single year urban adjusted instrumental temperatures to a 50 year average is just more anti-science.

If the global temperature keeps cheeping up and “nothing untoward” continues to happen… they will walk back and pretend the 1.5C limit never existed.

A little detail. The 2C was made up by Schellnhuber at PIK. He admitted it. Thought it made a nice ‘target’ when AR4 had ECS at 3. But then the EBM observational ECS studies came out at about 1.7, meaning 2.0 woild not be reached. aR5 refused to give an ECS estimate because of the discrepancy. It was then that the target was dropped to 1.5C so there would still be a climate emergency. This new ‘paper’ just underscores that made up emergency just in time for COP28.

It is possible that the climate will continue warming due to effects such as melting ice

I may be ignorant but when ice melts it absorbs heat. That’s why there are ice cubes in your whiskey-coke. As they melt, the drink remains just a little above 32F. Thus any ice on the planet absorbs heat as the phase change to water takes place. Melting of the Antarctic ice cap would absorb billions of calories of heat. On the other hand, the freezing of the oceans releases heat.

The term “due to the effects such as melting ice” implies that melting ice warms the climate when in fact the opposite is the case.

I don’t care what the Imperial College of London says or thinks, I don’t care what Drs. Lamboll or Rogelj think or say, I don’t care what the UN IPCC thinks or says. In other words all of these guys can take a hike.

The carbon budget is nonsense, a 1.5C increase is nonsense, a 2.0C increase is nonsense, the notion that a slight increase in temperature is catastrophic is nonsense and the notion that we even know what the average global temperature is is nonsense.

I would ask these CAGW experts what possible good taking their advice would achieve? Up to now we have wasted trillions of dollars listening to them and CO2 emissions haven’t gone down even a tiny bit. Exactly the opposite, CO2 emissions have increased without even a burp. Temperature has pretty much done it’s own thing, it has gone up, it has gone down and it has stayed the same, we have no control over the temperature.

To sum up all these guys can go to hell.

I am not sure out which hat they are picking the numbers for this exercise. The climate people state that the sensitivity of the climate to additional CO2 is 3°±1.5° for each doubling of the amount of CO2 in the atmosphere. (I know, but lets just go with it for a few minutes)

Doubling is a logarithmic relationship which we can calculate using on base 2 logarithms.

T1 • Temperature at time no 1. (currently approximately 288K, about 287 in the 19th century))
T2 • Temperature at time no. 2
C1 • CO2 concentration at time no. 1 (19th Century 280 ppm)
C2 • CO2 concentration at time no. 2 (currently 420 ppm)
ECS • Equilibrium Climate Sensitivity

Formula:
T2 = T1 + (ECS × (log2 (C2/C1)))
 plugging and chugging
T2 = 287 + (3 × (log2 (420/280)))
T2 = 287 + (3 × (log2 (1.5))
T2 = 287 + (3 × (0.585))
T2 = 287 + 1.755

So, we are stuck with going well past 1.5°, or their theory is just plain garbage.

We will see.

P.S. I am taking the under.
